To give it a try, hit up the Flickr Organizr's new "Map" tab. Flickr will ask what the privacy permissions should be on your photos' geolocation information (I love you for that Flickr).

Then find a photo location via search or map zooming and panning, and drag and drop it onto the map. The location will be listed with the timestamp and camera info on the bottom right. Users will be able to search photos by geolocation (ie, show me all the photos taken on the Brooklyn Bridge), too. See also the previous Lifehacker post on mapping your media, Map yourself.
